Definitions
- the present invention relates generally to locks and to other security devices that use locks and locking mechanisms. More specifically, it relates to an improved lock assembly that is used to secure the latch to the door of a truck storage compartment, or to secure other similar latches that are used for other purposes. It also relates to a lock assembly that is used to protect security seals used with such latches, including strap style seals, wire style seals and bolt style seals. It also relates to such a lock assembly that is unitary in construction such that the assembly is easy to use and eliminates the risk of loss of component parts.
- Latches that are used for securing truck storage compartment doors are well known in the art.
- One particular type of latch supports and secures a horizontal bar by means of two connected structures.
- One structure is a first hasp portion, which is a generally J-shaped holder, and the other is a second hasp portion, which is a generally L-shaped drop-down or hanging latch member.
- the L-shaped latch member is configured to be rotatably secured to the back portion of the J-shaped holder.
- the structures are provided with complementary apertures through which the generally U-shaped shackle of a conventional padlock can be inserted such that the two structures can be locked together.
- the apertures are also used to attach a security seal of some sort through the latch hasp portions after the truck storage compartment has been loaded. If this security seal is damaged in any way prior to the cargo arriving at its destination, or if the security seal is missing altogether, the cargo compartment contents may be considered “suspect” and the load may not be accepted.
- the present invention is the same as the prior assembly in that the base member that is attached via a hinge to a cover member.
- the cover member and the base member overlay the latch which prevents tampering of the latch and the security seal.
- the base member and/or the cover member each have cooperating cut-outs defined in adjacent side walls that allow the horizontal bar to extend through the cut-outs. In that way, the base member and the cover member can be “clamped” down over the latch such that the base member and the cover member can be locked together using a padlock.
- the cover side walls also include tabs which require that the cover be lifted vertically prior to rotation of the cover member about the base member.
- the present invention is an improvement over the structure mentioned above in that the cover member is capable of being rotated upwardly approximately 180° such that the cover is positioned out of the way when the user is attaching or detaching the security seal.

Abstract
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 13/383,680 filed Jan. 12, 2012; which is a 371 of PCT/US11/36098 filed May 11, 2011 which claims the benefit of and priority of U.S. Provisional Patent Application No. 61/333,810 filed May 12, 2010. The subject matter of each application is incorporated herein by reference.
- The present invention relates generally to locks and to other security devices that use locks and locking mechanisms. More specifically, it relates to an improved lock assembly that is used to secure the latch to the door of a truck storage compartment, or to secure other similar latches that are used for other purposes. It also relates to a lock assembly that is used to protect security seals used with such latches, including strap style seals, wire style seals and bolt style seals. It also relates to such a lock assembly that is unitary in construction such that the assembly is easy to use and eliminates the risk of loss of component parts.
- Latches that are used for securing truck storage compartment doors are well known in the art. One particular type of latch supports and secures a horizontal bar by means of two connected structures. One structure is a first hasp portion, which is a generally J-shaped holder, and the other is a second hasp portion, which is a generally L-shaped drop-down or hanging latch member. The L-shaped latch member is configured to be rotatably secured to the back portion of the J-shaped holder. The structures are provided with complementary apertures through which the generally U-shaped shackle of a conventional padlock can be inserted such that the two structures can be locked together. The apertures are also used to attach a security seal of some sort through the latch hasp portions after the truck storage compartment has been loaded. If this security seal is damaged in any way prior to the cargo arriving at its destination, or if the security seal is missing altogether, the cargo compartment contents may be considered “suspect” and the load may not be accepted.
- These inventors previously conceived a unitary, one-piece device or assembly for securely and inexpensively protecting the latch and latch hasp portions of a cargo or truck storage compartment door latch mechanism, and any security seal attached to the latch and its hasp portions. The assembly of that invention is disclosed in the applications referred to at the outset of this specification, which applications are incorporated herein by reference.
- The present invention is the same as the prior assembly in that the base member that is attached via a hinge to a cover member. The cover member and the base member overlay the latch which prevents tampering of the latch and the security seal. The base member and/or the cover member each have cooperating cut-outs defined in adjacent side walls that allow the horizontal bar to extend through the cut-outs. In that way, the base member and the cover member can be “clamped” down over the latch such that the base member and the cover member can be locked together using a padlock. In the preferred embodiment, the cover side walls also include tabs which require that the cover be lifted vertically prior to rotation of the cover member about the base member.
- However, the present invention is an improvement over the structure mentioned above in that the cover member is capable of being rotated upwardly approximately 180° such that the cover is positioned out of the way when the user is attaching or detaching the security seal. In the prior applications, the cover member is not capable of such full rotation, movement and positioning. The foregoing and other features of the improved hasp seal lock assembly of the present invention will be apparent from the detailed description that follows.
-
FIG. 1 is a perspective view of a latch and hasp seal mechanism known in the art. -
FIG. 2 is a perspective view of the base member of the improved hasp seal lock assembly of the present invention. -
FIG. 3 is a perspective view of the cover member of the improved hasp seal lock assembly of the present invention. -
FIG. 4 is a perspective view of the base member and cover member and showing cover member of the improved lock assembly in the fully “open” position. -
FIG. 5 is a view similar toFIG. 4 but showing the cover member in the fully “closed” position. -
FIG. 6 is left side elevational and cross-sectioned view of the improved assembly, such view showing the cover being partially lifted. -
FIG. 7 is a left side elevational and cross-sectioned view of the improved assembly, such view being similar to that ofFIG. 4 . - Referring now to the drawings in detail, where like-numbered elements represent the same structure throughout,
FIG. 1 is a perspective view showing a conventional latching or locking mechanism, generally identified 1, known in the art. The mechanism 1 is configured to be attached to the outer surface of a door of a cargo container or trailer (not shown) and comprises a generally J-shaped first hasp portion 2 and a generally L-shaped “drop-down” second hasp portion 6. The J-shaped first hasp portion 2 comprises aback 3 that is secured to the surface. The J-shaped first hasp portion 2 further comprises alower portion 4 and an outwardly-projecting lower lip 5. The lip 5 has an aperture (not shown) in it. The L-shaped second hasp portion 6 is configured to be rotatably secured to theback 3 of the J-shaped first hasp portion 2 via a fastener 9. The L-shaped second hasp portion 6 comprises back 7 and an outwardly-projectinglip 8 having anaperture 13 in it. The apertures of the hasp portions 2, 6 are used to thread ahasp security seal 12 through them when a latch arm 11 is positioned between the hasp portions 2, 6 as shown. It is to be understood that thehasp security seal 12 could be a strap style seal, a wire style seal or a bolt style seal of the type known in the art. -
FIGS. 4 and 5 illustrate a preferred embodiment of the improved hasp seal lock assembly, generally identified 10, of the present invention.FIG. 4 shows the improvedassembly 10 in a fully “open” position whereasFIG. 5 shows it in a fully “closed” position. The improvedassembly 10 comprises abase member 20 and acover member 40. When placed together as shown inFIG. 5 , thebase member 20 and thecover member 40 form a generally rectangular box-like structure that prevents access to the hasp portions 2, 6 of the latch mechanism 1 and to thehasp security seal 12 placed through the hasp portions 2, 6. - Referring to
FIG. 2 , it will be seen that thebase member 20 comprises a flatplanar back portion 22, an outwardly extendingtop portion 24 and an outwardly extendingbottom portion 32. Anopening 21 is formed within theback portion 22 to allow theassembly 10 to be mounted atop the latch and hasp seal mechanism 1 shown inFIG. 1 .FIG. 2 shows that thetop portion 24 of thebase member 20 includes a flat 25, a downwardly extendingfront leg 23 and a pair of downwardly extendingside legs 26. Each downwardly extendingside leg 26 further comprises an L-shaped aperture 27. The L-shaped aperture 27 comprises a substantiallyvertical aperture portion 28 and a substantiallyhorizontal portion 29. - A fastener, such as a bolt and connecting nuts, rivets or even a
single pin 18, may be received by this L-shaped aperture 27. SeeFIG. 4 . Thefastener 18 is also inserted generally horizontally throughapertures 47 that are defined within the roundupper portions 45 of the rearwardly extendingside walls 44 of thecover member 40. SeeFIG. 3 . Thecover member 40 can then rotate approximately 180° upwardly and downwardly about thefastener 18 relative to thetop portion 24 of thebase member 20. Thefastener 18 can also be flattened at each end to provide security for theassembly 10 once thefastener 18 is inserted. - The L-
shaped apertures 27 provide part of the means for locating thecover member 40 relative to thebase member 20 since they allow thecover member 40 to be elevated slightly vertically relative to thebase member 20. That is, thecover member 40 andfastener 18 can be elevated slightly vertically, thefastener 18 moving vertically within thevertical portion 28 of the slot-like aperture 27 defined in each of theside legs 26 of thetop portion 24 of thebase member 20. SeeFIG. 6 . The L-shaped apertures 27 also provide means for thefastener 18 to move horizontally within thehorizontal portion 29 of the L-shaped aperture 27. SeeFIG. 7 . - The
cover member 40 further comprises afront wall 42 having anupper edge 43. Thisupper edge 43 of thefront wall 42 is positioned lower than the upper edge of the assemblies described in the prior applications mentioned at the outset. That is, theupper edge 43 is shorter to allow thefront wall 42 to clear thefront leg 23 of the base member when thecover member 40 is raised to its fully open position. Thehorizontal portion 29 of the L-shapedaperture 27 also allows thecover member 40 to be moved forwardly of thebase member 20 which provides the necessary clearance to raise thecover member 40 to the point that it is shown, for example, inFIG. 4 . Once in the fully raised, or open, position, thecover member 40 will maintain its position while the user handles the hasp seal lock 1 andhasp security seal 12 as previously described. - Referring again to
FIG. 3 , it will be seen that thecover member 40 further comprises a pair oftabs 46, one extending downwardly from thelower edge 48 of each of twoside walls 44. Alatch arm opening 41 is also defined in eachside wall 44, theopening 41 allowing a portion of the latch arm 11 to extend through theassembly 10. Referring again toFIG. 2 , it will be seen that thebottom portion 32 of thebase member 20 comprises a forwardly extending flat having a pair of slot-like apertures 36 defined in it. Eachaperture 36 is configured to receive atab 46 of thecover member 40 within it. The use of thetabs 46 in theassembly 10 is important because it requires that thecover member 40 be lifted slightly vertically so that thetabs 46 can first disengage from theapertures 36 after which thecover member 40 can then be rotated and fully opened. A lock-receivingaperture 39 is disposed centrally within thebottom portion 32 of thebase member 20 as well. Thisaperture 39 aligns with a similar lock-receivingaperture 49 that is defined in the bottom of theface portion 42 of thecover member 40. Theseapertures cover member 40 andbase member 20 to be locked together using the shackle (not shown) of a conventional padlock (also not shown). - Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details disclosed and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept. In particular, it is to be understood that the other embodiments of the improved hasp
seal lock assembly 10 of the present invention specifically include those disclosed and claimed in the prior applications from which this application continues.
